Introduction:Preoperative screening and diagnosis of Keratoconus (KC) is particularly crucial for patients seeking vision correction by refractory surgery because postoperative corneal ectasia is one of the main complications resulting from operating an eye with undetected KC. The main origin of KC is still unidentified. One of the major risk factors that may predispose to this disease is family history, and this may be explained by the fact that up to 20 percent of people with keratoconus have a favorable family history. Aim of study:To assess the prevalence of keratoconus among patients seeking vision correction by LASIK. Subjects and Methods:This research is a cross-sectional study. The study included adult participants who received keratoconus screening as part of normal preoperative testing before receiving laser vision correction (LVC). Keratoconus was diagnosed with the help of an analysis of Pentacam-derived parameters.Results: About 20 patients out of 188 candidates presenting for LASIK were incidentally discovered as clinical or subclinical keratoconus cases and were excluded from performing the LVC procedure. The frequency distribution of keratoconus in patients seeking vision correction by LASIK was 11.9%. The most important risk factor predisposing to KC was family history. Conclusion:Patients seeking LVC had a high prevalence of keratoconus. An essential method for determining the prevalence of keratoconus in the Egyptian community is the screening of LVC candidates for keratoconus.

“…Ectatic disorders, traumatic corneal scars, and OSDs are not uncommon in children. [22][23][24][25][26] With fewer surgical options in children because of the higher risk of surgeries such as corneal graft rejection and postoperative inflammation, restoring vision/ocular health by contact lenses are gaining more importance. [27][28][29] Nonetheless, contact lens use and fitting in children is challenging, and data on fitting feasibility, safety, and efficacy in pediatric patients are scarce.…”

To report indications, fitting feasibility, and safety of miniscleral design (MSD) lenses in children. Methods: Medical records of patients aged ,18 years at the time of referral to Contact Lens Clinic of Farabi Eye Hospital, because of inadequate spectacle-corrected visual acuity, rigid gas-permeable or soft contact lens intolerance, and ocular surface disease were reviewed. Uncorrected visual acuity (UCVA), best spectacle-corrected visual acuity (BSCVA), bestcorrected vision with the lens (CCVA), lens parameters, and comfortable daily wearing time (CDWT) were documented. Results: Seventy-two eyes of 52 pediatric patients were fitted with MSD lens over a 9-year period. The indications for MSD lens fitting were keratoconus (29 eyes), corneal scarring from ocular trauma (16 eyes), ocular surface diseases (25 eyes), and postkeratitis corneal scar (2 eyes). The average UCVA and the mean difference between CCVA and BSCVA were 1.20 and 0.55 logarithm of the minimal angle of resolution, respectively, which shows statistically significant improvement. This significant increase in vision was even seen in those who were referred for the management of ocular surface diseases. The mean CDWT for most patients was 10 hr/day. Conclusion: Miniscleral design lens can be used as a safe and helpful modality to provide good vision and comfort in children experiencing ectatic disorders, traumatic corneal scars, and ocular surface diseases.
